GamersInfo is offering a new review of Civilization IV: Warlords, the first expansion for the latest in the popular nation building series. The game adds a variety of content to the main game including new scenarios, new playable nations, and the new warlord units. GamersInfo recommended the game to "all burgeoning mayors, city planners, or just plain gamers."

From the review:

The warlords and your civilization type, like Rome, give you certain special advantages or signature characteristics that hopefully help you succeed. Military commanders add skill and morale to units in the field. Engineers, artisans and tradesmen give you interesting missions to complete.

Warlords has three new leader traits, six new civilizations, four new leaders, eight scenarios, three new wonders, three new buildings including one unique building for each civilization, and three new units, including the great general or great person character. The now 24 possible civilizations have added Carthage, Celtia, Korea, Ottomans, Vikings and Zululand. Each new civilization has new leaders, and there are four new leaders for four existing civilizations: Ramses II, Churchill, Augustus and Stalin. Fourteen existing leaders incorporate new traits or have changed traits with other leaders.

The new scenarios limit you to a place in time. The technology tree is fixed to that time period, which I found limiting. Alexander the Great only has the technologies available to him and must complete his conquest of the known world in 200 turns. I found the historical scenarios otherwise interesting. Playing historical battles and civilization development was educational when comparing your progress to that of the historical events.
